LM2904BIDGKR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUT1	output	Output of op-amp channel 1. Push-pull class-AB output stage capable of sinking to within a few mV of V- and sourcing up to (V+ - 1.5 V) typical.
2	IN1-	input	Inverting input of op-amp channel 1. High-impedance input; PNP input stage allows the common-mode range to include V- (ground in single-supply operation).
3	IN1+	input	Non-inverting input of op-amp channel 1. High-impedance input; common-mode range includes V- (ground).
4	V-	power_in	Negative supply (or GND in single-supply operation). Supply range V+ - V- = 3 V to 36 V for the B variant (absolute max ±20 V or 40 V).
5	IN2+	input	Non-inverting input of op-amp channel 2. High-impedance input; common-mode range includes V- (ground).
6	IN2-	input	Inverting input of op-amp channel 2. High-impedance input; common-mode range includes V- (ground).
7	OUT2	output	Output of op-amp channel 2. Push-pull class-AB output stage capable of sinking to within a few mV of V- and sourcing up to (V+ - 1.5 V) typical.
8	V+	power_in	Positive supply. Operating range 3 V to 36 V (relative to V-); quiescent current typically 300 μA per amplifier.
